Keep same URL when form submitted

[glenelkins]

Hi

I want to keep a url as the same when a form is submitted, the form:

[code]
<form action='?a=shout' method='post'>
[/code]

this is all well and good though i have a file called 'module.php' which selects the module to display from 'module.php?mod=modtag' if i use the forum construct as above, it loads only module.php without the 'mod' so not displaying the same page but the default empty module

1) Alter the ACTION= ' ' part to include '&mod=modtag'      OR

2) Put a hidden input with value 'modtag' and name 'mod' into the form


[code]<input type='hidden' name='mod' value='modtag'>[/code]

No sorry, that wont work, the script does not know what module it is on at that poiint. Im writing a cms and one of the blocks runs a seperate script for a shoutbox. that script has no idea of the current module. Though i suppose i can get it to take $_GET['mod'];

Try:

[quote]echo '<form action="?'.(!empty($_GET['mod'])?$_GET['mod']:'').'&a=shout" method="post">';[/quote]

Not the best for readability but it does the job :).

Simply checks to see if the GET variable has a 'mod' value. If so returns it, if not returns an empty string. The result is concatonated and everything should work fine.

got it , if i leave action='' and set a hidden field to trap the action it works
